Airtel — Bill payment, already paid

Hi
My name is farhana Chishti,
I paid bill from sbi yono app for my airtel postpaid on 12 February 2023 630 inr and 12 march 1200 inr, both payments are successful, money has been debited but the biller airtel is still charging me with late fees, and overdue of bill. I have reference ids and transaction id of both payments. I can prove in court that I've already paid the bill
